Abstract: <P>PROBLEM TO BE SOLVED: To provide a fuel cell stack which prevents misfire of a burner of a modifier caused by condensed water generated in a gas manifold and restrains deterioration of a polymer electrolyte membrane and is excellent on reliability and durability.  <P>SOLUTION: The fuel gas manifold 1 includes a fuel gas inlet chamber 11 and a fuel gas outlet chamber 12 which are adjacently arranged via a partition 13, and a perfluorosulfonic acid membrane 14 is installed on a part of the partition 13. The fuel gas manifold 1 is arranged on one side face of the fuel cell stack 10, and a fuel gas turn chamber 18 is installed on a side face opposite to the fuel gas manifold 1. A fuel gas introduced to the fuel gas inlet chamber 11 is returned to the fuel gas outlet chamber 12 by being U-turned to the fuel gas turn chamber 18 after distributing to a fuel passage of each single cell. At this time, the fuel gas is humidified without damaging hydrogen gas concentration in the fuel gas since moisture included in a fuel exhaust gas is transferred to a fuel inlet gas on the basis of a humidity difference between the fuel gas inlet chamber 11 and the fuel gas outlet chamber 12.  <P>COPYRIGHT: (C)2010,JPO&INPIT
